Hello!
On my LG Leon 4G LTE H340n there is a problem with booting, it stuckts at LG booting logo. When I try to put it in download mode (volume up and connect usb) it displays security booting error and then black screen showing only.
So I can't get it into download mode, can't boot it, and I tried putting it in fastboot (with volume down and connect usb), but that fastboot mode doesn't really work it gives failed command not found on every command.
So how is it possible to reflash the stock recovery (to allow download mode) and then the ROM?
I already have the needed .img files (laf.img, recovery.img, etc..)
I read on other threads that it is possible to write those img files to the correct partition but you need to short testpoint. So how to do this on this phone?
Thanks in advance!
To me the time that I came out this error was installing a Custom Recovery and could not fix it I had to send it to sat and I made a change of motherboard do not know if there will be someone alla able to fix it but I think since you can not access the fastboot or the dowloads mode. Sorry for my English but this translated with google translator
I never need to enter into download mode in my lgms345 to flash a kdz file and all occurred fine!
Lg flash tool put the phone automatically into download mode but your phone need to. Stay connected to your PC

Hi guys,
Long-time phone rooter/XDA reader, first time posting.
It seems I have finally come across a problem I can't fix by insane amounts of googling and trial&error.
I am currently on some Kitkat custom ROM variant with CWM 6.0.4.4
I'm looking to get back to stock, but my download mode refuses to open. Its stuck at the blue dots screen. (attached picture for clarity)
I've let it sit there overnight, with no change.
I've attempted to use the LGMobile Tool (even this method), but when it reboots my phone, the phone sits on the "LG" screen, and the LG tool eventually errors out ("communication error").
Recently, I managed to back myself into a corner after (incredibly idiotically) accepting an OWA, when my recovery was corrupt, and my download mode would not even open then - and i had to use some bizarre method of commands in Linux to be able to get TWRP on, then flashed CWM and them my ROM.
So what can I do now? I'm assuming my download mode is corrupt - is there a way to flash a good download mode onto the phone?
Any thoughts/input greatly appreciated.
edit:
Ok looks like I have understimated myself.
I used THIS tool to extract my KDZ, to get the LAF file (then renamed it to laf.img)
I then used the instructions from HERE to flash to the correct place.
It did not reboot into download like the thread said it would, but I did a manual download mode entry (while off, hold Volume Up + insert USB) and viola!

Hey thanks for the post. My download mode will not go past the 5 blue dots screen. I am trying to return to stock but I get the same download mode error. I am rooted and have TWRP installed. This download mode error has happened before. I fixed it by flashing CM and then going into download mode and it worked! But my TWRP is getting an error when installing any rom. It fails and installation and says error executing updater binary. I just need to fix download mode or TWRP. Any help would be great.
Did you already have recovery installed when you were stuck at the 5 dots download mode screen?

Hello guys, i got a big problem with my lg g2.
When I turn it on, it gets stuck at the Lg Logo and nothing happens from there.
I tried going to download mode and flashing a stock rom but to no avail.
I tried this : http://forum.xda-developers.com/showthread.php?t=2432476
but when the phone actually restarts at the end of the process, it gets stuck at the logo again and the light keeps on flashing.
I also tried the TOT method to flash the mobile to stock rom but i always get "LAF retrieveGPT() failed"
Every time i switch the mobile on, it stays at the lg logo
Does anyone knows what i should do now?
Thanks in advance for any help given.
Have you try to hard reset after kdz flash?
Did the hard reset but when the phone starts, it gets stuck at the logo screen again.
I just tried to flash again with another TOT and it actually worked until the phone restarts by itself and gets stuck at the logo again.
That is, on the flash tool it shows that the phone is restarting to complete the installation but the phone just gets stuck at the logo and then after a few seconds the flash tool shows that the process has failed.
Any suggestions?
I'm having the exact same problem:
When I turn the phone on, it is stuck on the LG screen
I cannot enter recovery mode (holding power + volume down...)
I cannot enter download mode - it shows fastboot screen instead
I'm completely lost as what to do??? I think I've just wasted a phone
I can't do any of the fixes that I can find because I'm not able to enter download mode, the LGMobile Support Tool wont recognize my phone etc
Hello mate, there's an easy fix to be able to get download mode.
Download this and extract it in your local disk ( C:\boot )
((seems like i can't post links before 10 posts))
Go on google and download fastboot to your pc and find a laf.img for your phone varient
Then open cmd and type:
cd C:\boot
fastboot erase recovery
fastboot erase laf
fastboot flash laf laf.img
fastboot reboot
That will fix your download mode immediately.
But I do not know any further. Once you get access to download mode, try flashing the kdz or even TOT files and let me know if you are able to pass the logo screen.
Cheers

Sorry, I don't know what you're saying. If you can somehow direct me to the link that would be great! :good:
if you give me the name of another thread, I should be able to search for it
I finally found it lol.

Just follow the steps but you need to find the laf.img for your phone varient. The laf in the link is not for D802.

that worked! I'm now using the LGMobile support tool to try and reinstall the original firmware - I will let you know how it goes once that's complete
EDIT: It said that software install was complete, but I'm still stuck on the LG Boot screen
EDIT 2: just tried the steps from here: http://forum.xda-developers.com/showthread.php?t=2432476 - it now loads the LG boot screen, then and android guy (with hexagonal shape?) and blue bar underneath, and then back to the LG Boot screen
IM GOING CRAZY HERE!!! what am I supposed to do to fix this
Yeah, i'm stuck just like you.
Just sent it for repairs at a local shop because I also was going nuts over this.
If it becomes alright, I'll ask the guy to explain what he did and I'll write it here in a few days.
Patience my brother.

Thanks :good: I have already done this (as you can see above), however I cannot complete the last step which is flashing the new firmware. I'm still left with the LG logo after doing this
Any updates?
Well guys, its been a long time since I'm having this problem and I didn't find any solution.
Anyone knows how i can fix this?
Or any suggestions?
Thanks in advance
Hi,
I tried to install Grola Rom on my phone and unfortunately I think that I may have flashed the ROM for the D802 (I tried to find a faster DL than the FShare link).
My phone is now stuck in Fastboot Mode. I've tried every method to try to get my phone back into regular working condition, but my laptop does not recognize my phone. No matter which driver I install, it shows up as Android in device manager and ADB devices and Fastboot devices shows up nothing.
I was able to get it to boot into download mode for about two seconds before it boots itself back into download mode immediately.
I've tried accessing recovery and download mode, but nothing works.
How would I either get back to recovery or at the very least back to download mode so I can go back to stock?
Thanks,
mjoecarroll
Edit: When I boot up it just says Fastboot Started.
When I plug it in, it says:
--reset--
--portchange--
--reset--
--portchange--
Same problem did you fix it?
So I wiped the system partition on my LG G2/D800 (mostly out of stupidity) and now I'm stuck in the boot loop.
Symptoms are following:
1. Stuck in the boot loop
2. Will not go into download or recovery mode
3. When turning on the LG logo appears and disappears repeatedly
4. Device is not detected when plugged into the USB
5. Factory reset using VolDown+Power doesn't do anything
I've tried most of the ideas I've been able to find on the forum, but it looks like I'm stuck mostly because I cannot enter download mode and the phone is not detected in any way when plugged into the USB (no many partitions or anything).
Will be grateful for any ideas how to get out of it?

so vol up and then plug usb, does not take you to download mode?
if not try using srk tools.. if that doesnt work i think you need to short circuit your motherboard.

and to go back to stock d800 variant..you said you have..

Indeed I cannot enter download mode with vol up then plug usb.
Good news is that I was able to enter qhsusb mode by short circuiting the moterboard. I used srktools to unbrick in qhsusb mode, however it didn't work. The linked guide recommends to flash only laf.img, aboot.img and boot.img. I don't really understand how flashing more can hurt. I also don't completely understand why flashing these should help. After all, I messed only with the system partition. I'll try to follow the guide more closely, but I'm thinking that a better idea would be to flash system partition in a qhsusb mode. I just need to figure out where to get system.img from.

So now I can consistently get into ghsusb mode by short curcuiting the motherboard, and I can flash img files with dd. I flashed every partition from the stock FW which was on my phone. Now when hold vol up and plug in usb, I'm ending up in a stock recovery. However, I still cannot enter download mode and the phone still suffers from boot loop if I choose to reboot the phone.

Hey,
I hard bricked my phone, the one where you connect to the PC 15 or so drives open up (no download mode, no recovery and no fastboot) and then managed to fix it (VIA SRK Tool which flashed a stock recovery instead of a custom one) and got download mode back.
KDZ Method isn't working, it keeps saying I need to restart my device 2%.
So is there any way of flashing the TWRP recovery through the download mode or at the very least any way to extract my data (only a few folders) through the download mode?
I don't know why but no one seems to notice this thread
Thanks a lot, any help will be much appreciated.
PS: Please ask if any further information is required
(I have a D801, I can get to download mode, factory reset screen and LG logo which then leads to the "Security error" coz there is no firmware in the phone.)
